Abstract

A magnetic-field-adjustable micromagnetic orthodontic accelerator includes a cheek side plate, a tongue side plate and a supporting plate to form a structure of teeth sleeves, cheek side magnets and tongue side magnets are arranged on the cheek side plate and the tongue side plate respectively, the cheek side magnets and the tongue side magnets form a micro magnetic field environment around roots of to-be-moved teeth receiving orthodontic treatment, physiological magnetic field loss caused by traction of the orthodontic accessory is effectively compensated, metabolism and reconstruction of periodontal tissue of the to-be-moved teeth are promoted, and the orthodontic teeth moving process is accelerated.

First claim

What is claimed is:

1. A magnetic field adjustable micro-magnetic orthodontic accelerator, comprising:
a buccal side plate and a lingual side plate arranged opposite to each other, with buccal side magnets installed in the buccal side plate and lingual side magnets installed in the lingual side plate, wherein the buccal side magnets and the lingual side magnets are positioned opposite to each other in pair, and at least three pair of the buccal side magnets and the lingual side magnets are provided; and
a support plate for connecting the buccal side plate and lingual side plate, to form an accommodating space defined by the support plate, the buccal side plate, and the lingual side plate, giving the magnetic field adjustable micro-magnetic orthodontic accelerator a dental brace structure;
wherein when the magnetic field adjustable micro-magnetic orthodontic accelerator is in use, teeth are placed within the accommodating space, with the buccal side plate and lingual side plate separately positioned on a buccal side and a lingual side of the teeth within the accommodating space, and the buccal side magnets and the lingual side magnets correspondingly positioned to roots of the teeth; and micro-magnetic fields acting on the roots of the teeth are formed between the buccal side magnets and the lingual side magnets in pair;
the buccal side plate and the lingual side plate each comprise an anterior tooth area, a premolar area, and a molar area; the buccal side magnets and the lingual side magnets are arranged opposite to each other in the anterior tooth area, the premolar area, and the molar area;
a number of the buccal side magnets and a number of the lingual side magnets are both 3 to 12;
a micro-magnetic field formed in the anterior tooth area has an intensity of 20-25 mT, a micro-magnetic field formed in the premolar area has an intensity of 15-20 mT, and a micro-magnetic field formed in the molar area has an intensity of 10-15 mT;
the buccal side magnets are detachably installed on the buccal side plate, and the lingual side magnets are detachably installed on the lingual side plate;
the buccal side plate and lingual side plate are provided with tapered grooves; the buccal side magnets and lingual side magnets are inserted into the buccal side plate and the lingual side plate through the tapered grooves, with open edges of the tapered grooves forming locks for the buccal side magnets and lingual side magnets; and
the support plate, the buccal side plate, and the lingual side plate are made of a silicone material, and the silicone material comprises soft silicone or hard silicone.

2. The magnetic field adjustable micro-magnetic orthodontic accelerator according to claim 1 , wherein the buccal side plate comprises an upper buccal side plate and a lower buccal side plate that are symmetrically arranged with respect to the support plate; the lingual side plate comprises an upper lingual side plate and a lower lingual side plate that are symmetrically arranged with respect to the support plate; the accommodating space comprises a first accommodating space and a second accommodating space arranged in upper and lower positions respectively, with the upper buccal side plate, the upper lingual side plate, and the support plate forming the first accommodating space, and the lower buccal side plate, the lower lingual side plate, and the support plate forming the second accommodating space; the first accommodating space is used for placing maxillary teeth and the second accommodating space is used for placing mandibular teeth.

3. The magnetic field adjustable micro-magnetic orthodontic accelerator according to claim 1 , wherein in the buccal side magnets and the lingual side magnets in pair, in a connection direction of each of the buccal side magnets and a corresponding one of the lingual side magnets, magnetic poles of each of the buccal side magnets and the corresponding one of the lingual side magnets are set along a same direction.
